Bright White Light Moving at High Rate of Speed East to West Above Route 40 @ Route 29 in Ellicott City.

I was driving North on Route 29 just before Route 40. I saw a round bright white light from the east above Route 40 headed west above Route 40 at an extremely high rate of speed. It did a tiny little loop and kept going west. It may have been a second or three but it was so fast. It was too close to the ground to be an aircraft and also too small. It was just a bright white light, not so bright that it hurt the eyes though. It was like a super sized version of an LED light. I was shocked that I could not find any other reports of this event online.
